R java not updating
Applies to Windows or Mac OS X 10.7.3 and above Starting in Java 7, the Java Control Panel includes the Security option, "Enable Java content in the browser", which is selected by default.De-selecting this option will prevent Java applets from running in any browser and the Java plugin will no longer appear in the Firefox or Sea Monkey Add-ons Manager or about:plugins list.You can also download an offline installer using the "JRE" download link on Oracle's Java SE Downloads. Even if you have a 64-bit operating system, you need the 32-bit (x86) Java download for 32-bit browsers.On Windows, make sure you select the 32-bit JRE since Firefox and Sea Monkey official releases are 32-bit (e.g., select "Windows x86 Offline" for the offline installer linked from Oracle's Java SE Downloads page).If you only see the Java Deployment Toolkit plugin listed in the Add-ons Manager, then Java is not properly detected.To disable the Java plugin in your Mozilla browser, open the Add-ons Manager, find the Java plugin entry as described above and then, depending on the browser version, click the "Disable" or "Never Activate" button.If you have any trouble with these songs, try changing the instrument patch with any sequencing software or E-mail me and let me know of the problem.These are the lecture notes I use in my course, Introduction to Java Programming, taught most semesters at Polytechnic University in Brooklyn (formerly known as Brooklyn Poly).

Plug-ins can cause crashes and hangs and may contain security vulnerabilities.
Information on security and stability issues affecting Java is available at Oracle's Critical Patch Updates and Security Alerts page.
On Windows, the Java plugin will be listed as Java(TM) Platform SE Note: Starting in Firefox 23 and Sea Monkey 2.20, the button to "Disable" or "Enable" plugins has been replaced with a drop-down menu with the click-to-play options "Always Activate" to enable, "Ask to Activate" to set click-to-play, and "Never Activate" to disable (bug 549697).
After enabling Java, test Java again: The Java Deployment Toolkit plugin, which is installed along with Java, does NOT need to be enabled for Java applets to work.
